| Abstract: | The test studied on the vitro antioxidative activities of proteins extracted from Momordica charantia.L seeds. The results indicated that three proteins extracted by saturated ammonium sulphate had the different antioxidative activites in three anti-oxidation systems. As a whole, protein precipitations by 90% saturated ammonium sulphate have the-stronger activities, while which by 60% saturated ammonium sulphate have the weakest activities. |
